Question

Find f'(x), f(x)= (4-x)/(3+x)

Answer 1

Do you know the quotient rule?

Answer 2

I used f'(x)=lim h->0 (f(x+h)-f(x))/h

Answer 3

Does it have another way to solve it?

Answer 4

Ah, you're using the definition. So I take it you haven't learned the quotient rule yet?

Answer 5

I think so

Answer 6

Actually I'm taking cal3 now
This question have a condition

Answer 7

Do not use the definition of the derivative

Answer 8

Ah, well perfect. Use the quotient rule.
